AI Technical Summary

Technical Problem

Existing agricultural mowing devices face challenges in efficiently and cost-effectively integrating a flail curtain into their lateral transport systems, which are often separate and increase operational costs due to the need for additional transport trailers.

Method used

A stowable flail curtain system is integrated into the mowing device's lateral transport system, featuring a sheet of rigid material supported by arched arms and actuation mechanisms, allowing it to transition between a deployed position for blocking debris and a stowed position for transport, facilitated by hydraulic or electric actuators.

Benefits of technology

The system enables efficient width reduction for transportation, reducing operational costs by eliminating the need for separate transport trailers and ensuring seamless transition between field and transport positions.

Abstract

A stowable flail curtain for blocking debris flailed by a conditioner of an agricultural mower when in use. The flail curtain includes a sheet of material, a first arched support arm coupled between the sheet at a first attachment point and the trail frame, a second arched support arm coupled between the sheet at a second attachment point and the trail frame, and first and second actuation mechanisms coupled to the first and second arched support arms, respectively, and to the trail frame to move the sheet between a deployed position that blocks debris flailed by the conditioner when in use and a stowed position under the trail frame.
